ADUM4400WBRWZ-RL

Overview

The ADUM4400WBRWZ-RL is a quad-channel digital isolator from Analog Devices, utilizing iCoupler magnetic coupling technology. It provides four independent signal paths with unidirectional data flow. The device operates within a supply voltage range of 2.7 V to 5.5 V and supports data rates up to 10 Mb/s. It features an isolation voltage rating of 5000 Vrms and offers a propagation delay of 32 ns. Packaged in a wide-body SOIC-16 (SOIC-16W) surface-mount format, it is designed for robust noise immunity in industrial applications.

Feature Summary

• Integrates four isolated channels using proprietary iCoupler magnetic coupling technology for high-speed signal transmission.
• Provides galvanic isolation with a rated insulation voltage of 5000 Vrms to protect low-voltage circuits from high-voltage transients.
• Features bidirectional logic interface capability within the specified operating temperature range for flexible system integration.

Applications

• Industrial automation systems requiring robust signal isolation between microcontrollers and sensors.
• Power electronics interfaces for monitoring and control in motor drives and inverters.
• Medical equipment where patient safety isolation standards are critical for signal integrity.

Procurement Notes

Verify the specific suffix WBRWZ-RL against official Analog Devices documentation to confirm package type and reel configuration. Ensure compatibility with existing PCB footprints for the wide-body SOIC-16 variant. Check current availability status as distribution may vary by region. Confirm RoHS compliance details through the manufacturer's latest datasheet before finalizing procurement orders.

Selection Notes

Select this component when four isolated channels are required with a 5 kVrms isolation barrier. Consider the 10 Mb/s data rate limit for application speed requirements. Evaluate the 32 ns propagation delay against timing constraints. Compare power consumption characteristics against other iCoupler variants if thermal management is a primary design constraint.

Part Context

This part belongs to the ADuM4400 series of quad-channel digital isolators. It represents a standard offering in Analog Devices' portfolio for general-purpose isolation needs. The series is known for replacing traditional optocouplers in many applications due to smaller size and higher reliability. It complements other channel-count variants like dual or single-channel isolators in the same family.

FAQ

What is the maximum data rate supported by the ADUM4400WBRWZ-RL?

The device supports a maximum data rate of 10 Mb/s per channel.

Does the ADUM4400WBRWZ-RL include an integrated isolated power supply?

No, the ADUM4400 is a signal-only isolator and does not contain an integrated DC/DC converter; external power supplies are required for both sides.
